Title: Photographic shutter with shutter blades reversing during successive exposures
IPC: G03B9/20
Filed: 1965-11-16
Abstract: 1,077,318. Photographic shutters. PRONTOR-WERK ALFRED GAUTHIER G.m.b.H. Nov.16, 1965 [Dec.28, 1964], No.48601/65. Heading G2A. A photographic shutter of the kind having blades 4 which are pivoted through 180‹ to open and then close the shutter by rotation of a ring 5, the next exposure being effected by rotating the ring in the opposite direction, thereby causing the blades to take up their original positions, is provided with a lever 12 for reversing the direction of rotation of the ring, the lever having two stops 13, 14 which, for successive exposures, alternately engage with arms 11a, 11b respectively of a rod 11 driven by the shutter tensioning lever 9. To cock the shutter, the lever 9 is rotated about a pivot 7 thereby moving the rod 11 to the right as shown. A cam (18) Fig.4 (not shown) strikes the pin (13) and is pivoted anticlockwise to tension a spring (20). The rod 11 then loses contact with the pin 14 and is rotated about a pin 10 by the spring (20), which rotation brings pin (14) and rod (11) in contact again, Fig.5 (not shown) simultaneously with the lever 9 being latched in its cocked position. To release the shutter, a lever 24 is rotated in a clockwise direction, thereby moving a lever 27 out of the path of a pin 29 on the ring 5 and releasing the latch on the lever 9. The latter then returns to the position of Fig. 1 under spring action, thereby moving rod 11, and hence pin (14) to the left (as seen in Fig. 5). This rotates the lever 12 which carries with it a pin 16 of the ring 5, thus rotating the ring anticlockwise. When the shutter is reclosed, the pins 16, 29 are at the opposite ends of slots 2b, 2c from the position shown. During the next cocking action the lever 9 is rotated as before, but this time a cam (19) (Fig. 4) strikes the pin 14, so that at the end of the cocking movement the rod 11 abuts the pin 13. Releasing the shutter causes an action similar to that described above but modified in that the lever 12 is rotated anticlockwise and the ring 5 clockwise. The blades 4 again assume the position of Fig. 1.

Title: A process for the decomposition of complex compounds of hexafluoroantimonic acid and hydrocarbons
IPC: B01J27/06
Filed: 1964-11-30
Abstract: Complexes of hexafluoroantimonic acid and hydrocarbons formed during the conversion of hydrocarbons using hexafluoroantimonic acid catalyst are decomposed in the presence of hydrogen on a hydrogen containing gas, with aid of tetrafluoroboric acid, at a temperature of at least 20 DEG  C. producing antimony trifluoride and lower molecular weight hydrocarbons.  The hydrogenating decomposition may take place in the presence of 1 to 10 parts by volume per part by volume of complex of a solvent having a viscosity lower than that of the complex, as diluent, e.g. liquid hydrofluoric acid, which may be present initially as a diluent for the hexafluoroantimonic acid catalyst which is being used for the conversion of hydrocarbons. The tetrafluoroboric acid may be generated in situ by introducing gaseous boron trifluoride into the hydrofluoric acid-containing solution of the complex.  The decomposition of the complex produces hydrogen, hydrofluoric acid, borontrifluoride, hydrocarbons (gaseous and liquid) and antimony trifluoride.  Hydrogen fluoride may be separated from the gaseous constituents by cooling, then borontrifluoride may be separated by adsorbtion in anisole and recycled.  The remaining hydrogen and hydrocarbons may be reintroduced into the first stage. The antimony trifluoride may be converted with chlorine to SbF3Cl2 which may be converted to antimony pentafluoride or hexafluoroantimony acid with calculated amounts of liquid hydrofluoric acid.ALSO:Complexes of hexafluoroantimonic and hydrocarbons formed during the conversion of hydrocarbons using hexafluoroantimonic acid as catalyst are decomposed in the presence of hydrogen (or a hydrogen containing gas) with the aid of tetafluoroboric acid at a temperature of at least 20 DEG C. into antimony trifluoride and lower molecular weight hydrocarbons.  The hydrogenating decomposition may take place in the presence of 1 - 10 parts by volume per part by volume of complex of a solvent having a viscosity lower than that of the complex, as diluent, e.g. liquid hydrofluoric acid which may have been present initially as a diluent for the hexafluoro-antimonic acid catalyst.  The tetrafluoroboric acid may be generated in situ by introducing gaseous boron trifluoride into the hydrofluoric acid containing solution of the complex.  The antimony trifluoride produced in the decomposition may be converted with chlorine to SbF3Cl2 which may be converted to antimony pentafluoride or hexafluoroantimonic acid with calculated amounts of liquid hydrofluoric acid.

Abstract: 1442189 Handling device for nuclear fuel elements and control rods EISENWERK WESERHUTTE AG 25 Oct 1973 [20 Jan 1973] 49700/73 Heading B8H A handling device, for lifting, lowering and transporting fuel elements and control rods in a nuclear reactor, comprises respective grippers for the fuel elements and control rods mounted in a telescopic tube and controlled such that when one is operative the other is inoperative. The telescopic tube 1, 2 is suspended from an overhead hoist carriage (not shown) and the grippers from part of a head 3 rotatably mounted on a plate 9 suspended within the tube by cables 6 connected to the winch carriage. Further cables 7, also connected to the winch carriage, are connected to a lever 11 to pivot same about its mounting on the plate 9 between two end positions corresponding respectively to the operative positions of the grippers. The lever 11 is connected through a swivel head 21 to a coaxial sleeve 22 and rod 23 which actuate the fuel element gripper and the control rod gripper respectively. The sleeve 22 is connected to a cam 30 which in the end positions of the lever 11 engages respective followers on pivoted arm 12 to move same to operative or inoperative positions such that hooks 33, 34 thereon can be engaged or disengaged from a fuel element 13. Pins 36 on the arms co-operate with catches 37 on a control rod guide 35 to release same from engagement with the tube in order that the guide can be lifted with the fuel element. The rod 23, on the other hand, co-operates with balls 15 in radial bores in a tube 16 to urge same, in its operative position, into an annular groove in a control rod head 14. A sleeve 19 slidable on the tube 16 ensures that the balls remain in the radial bores when the tube is disengaged from a head 14 and also ensures that the balls are in alignment with the annular groove in the head 14 when the tube is inserted therein. The sleeve 19 is coupled to a disc 25 which is locked to the rod 23 in the end position of the lever 11 by farther balls 28 and has apertures to receive a pin 29 mounted on the arms 12 to lock the latter in the operative or inoperative positions. For maintenance of the grippers the head can be raised whereupon the lever 11 contacts lugs (54), Fig. 1 (not shown) to retract the telescopic tube. Pins (52) can then be inserted to retain the tube in its retracted condition and a dummy fuel element and control rod head used to list the head 3.

Abstract: 1279427 Static rectifiers SIEMENS AG 9 Oct 1969 [19 Oct 1968] 49724/69 Heading H2F [Also in Division C7] Relates to short-circuit protection in an A.C./D.C. static converter arrangement for electrophoretic lacquering plant comprising controllable rectifier units 9, 10, 11 connected between respective conveyer rails 5, 6, 7 and a dipping tank 2 and which receive firing pulses simultaneously from a common pulse unit 15 controlled in dependence upon deviations of actual A.C. input current and D.C. output voltage from desired values, by circuits 14, 13. In the event of a short-circuit between one of the rails and the tank, firing pulses to the rectifier unit connected to that rail are prevented by the opening (e.g. by overcurrent protection units, not shown) of a remotely controlled switch 31, 32 or 33 in the control lines to that rectifier unit. The circuit 13 receives a desired output voltage signal from a potentiometer 17 and actual output voltage signals via decoupling diodes 20, 21, 22. The output of circuit 13 is used as a desired current value and fed into a current controller 14. The actual input current to the rectifier units is sensed by C.T.s 28, 29, 30 and fed via diodes 24, 25, 26 to a common link, the maximum of the three currents being compared with the desired value in the circuit 14. Instead of the A.C. input currents the direct current outputs of the rectifier units may be sensed and fed back. The rectifier units may be in semi-controlled bridge configuration with a common uncontrolled bridge half, the controlled bridge halves being connected to respective conveyer rails. Each switch 31, 32 or 33 comprises a plurality of contact pairs one pair connected to each rectifier element.

Filed: 1972-10-31
Abstract: 1397255 Digital data storage INTERNATIONAL BUSINESS MACHINES CORP 31 Oct 1972 [10 Nov 1971] 50055/72 Heading G4C Digital data is stored in discrete records on a record medium (e.g. magnetic discs) and a counter, during normal operation, starts a fresh count on the detection of a fresh record. If the processing of a record is interrupted, e.g. for error correction, the counter continues counting until it indicates that one or more full cycles of the record medium are about to be completed when a gating period is commenced. If the start of the record is detected during this period the system can then be resynchronized. Each disc track is headed by a home address field for address identification, a track descriptor record to indicate the physical condition (such as defective or defect free) of the field, and an index point. Following these are data records, each including a synchronization area, an address marker, a count field, a key field and data fields. The track is also divided into sectors. When an error in a record is detected, the error condition is processed, then resynchronization is effected, and the corrected data (if any) is rewritten or reading of the records continued. The counter (11, Fig. 3, not shown) is driven by a phase locked oscillator whose output frequency varies with variations in disc speed. The current sector value is also stored in another counter. On Fig. 4, S is the sector in which the previously interrupted record is stored and S-1 is the preceding sector. When an error is detected set sector apparatus as described in Specifications 1,279,228 and 1,310,869 compares the read sector values with S-1 and, when the leading edge is detected, the microprogram is interrupted. A period T is then commenced and, at the end of this, a period W1 (within which the start of the desired record should lie) is commenced. During this period the counter (11) is checked continuously for a reading indicating that the address marker of the desired record is just about to appear. If period W1 finishes before this happens the procedure is aborted. If it is about to appear in period W1 another period W2 is commenced during which the address marker is searched for and, if it appears in W2, resynchronization is complete. If not, the procedure is repeated a predetermined number of times until it appears or a hard error is signalled. In another embodiment (Figs. 4A, 4B, 5A, not shown) shorter sector lengths are simulated to avoid the situation where there is more than one address marker in period W1.
